Answer:

A tropism is a growth toward or away from a stimulus. Common stimuli that influence plant growth include light, gravity, water, and touch. Plant tropisms differ from other stimulus generated movements, such as nastic movements, in that the direction of the response depends on the direction of the stimulus

Answer:

The three stimuli that cause the plants to exhibit tropism are:

1. Touch: This stimulus triggers thigmotropism, which is the turning or bending of the plant and tendrils in response to the touch.

2. Light: This stimulus triggers phototropism. It is how the plant reacts toward the direction of the light source. In this case, the stem may bend in response to the direction of the light.

3. Gravity: This stimulus triggers phototropism gravitropism, which is responsible for the downward growth of roots into the soil.

Does the study of disease require Science? If yes, why?

Stella [2.4K]

First of all science is needed to study most things including diseases and this is so since the study of diseases would require a research organism of course and this is any creature that scientist would use to study life and so without science this would not be possible as science allows for the study of animals and humans which are likely to be vectors and diseases requires epidemiology which are scientific disciplines similar to biology to better understand the disease processes and so science is definitely needed.

ololo11 [35]

Answer:

If the calcium levels in blood increases, then there is increase in blood glucose level.

Explanation:

Calcium in blood plays a vital role of homeostasis in regards to level of secretion of insulin. If the calcium level is altered, the homeostasis mechanism is hampered. Several researches have shown that alteration of serum calcium level affects the metabolism process of carbohydrate and makes the person vulnerable to risks of diabetes mellitus and associated complications. Hence during calcium supplementation, the person's blood glucose level must be considered.
